C. Joseph Vijay was sworn in as Chief Minister of Tamil Nadu on May 10, 2026, at Chennai’s Jawaharlal Nehru Indoor Stadium, marking the first time a party outside the DMK-AIADMK duopoly has led the state since 1967. His Tamilaga Vettri Kazhagam (TVK) emerged as the single-largest party with 108 seats and secured a working majority through support from the Congress, CPI, CPI(M), VCK and IUML. Governor Rajendra Vishwanath Arlekar administered the oath; nine ministers were appointed including N Anand, Aadhav Arjuna and KA Sengottaiyan. Vijay immediately approved 200 units of free electricity for domestic consumers and set up task forces on women’s safety and drugs, and pledged to publish a white paper on the state’s finances amid his claim of heavy debts. The swearing-in drew political leaders and film personalities, with large public celebrations; assembly oath-taking of MLAs followed on May 11. The new government faces an early floor test and scrutiny over coalition durability and fiscal plans.

Fine Gael’s Seán Kyne has been elected to the Dáil in the Galway West byelection after the 11th and final count, defeating Independent Ireland’s Noel Thomas. Kyne finished on 19,218 votes to Thomas’s 16,519, a margin of 2,699, aided by 4,249 transfers from Labour’s eliminated candidate Helen Ogbu. The result closed a contest that swung between Thomas, who led through much of the count on transfers from smaller and anti‑establishment candidates, and Kyne, a long‑standing local TD and senator whose name recognition and record of delivering local projects proved decisive. The count also saw significant transfers from Fianna Fáil’s Cillian Keane and evidence of both a left‑leaning “vote left, transfer left” pattern and tacit transfers between centrist parties. In Dublin Central, the Social Democrats’ Daniel Ennis won the separate byelection held the same weekend. Fine Gael leader and Tánaiste Simon Harris described the Galway West outcome as a boost for centrist politics and party renewal. Labour’s Helen Ogbu performed strongly for the left, finishing third after transfers and signalling potential gains ahead of future contests.

On the evening of May 23, 2026, NBC News correspondent Julie Tsirkin was filming on the White House north lawn when multiple gunshots rang out nearby. Video of her stunned reaction — asking “What is that?” as pops echoed in the background — was captured in real time and has since circulated widely on social media. Authorities identified the shooter as 21-year-old Nasire Best, who approached a Secret Service checkpoint, opened fire and injured an adult male bystander who later underwent surgery and was reported in stable condition. Uniformed Secret Service officers returned fire and killed the suspect; President Donald Trump was in the White House at the time and was not harmed. Reporters in the area were ordered into the press briefing room as the compound was secured. Footage from other journalists, including ABC’s Selina Wang, corroborated the sequence of events. Media outlets noted the clip quickly spawned memes and critical commentary about on-air reactions while officials continue to investigate the motive and the suspect’s background.

Douglas Shepp McCain, the eldest adopted son of the late U.S. Senator John McCain, died suddenly on May 20 at age 66, his family said. The announcement was shared publicly by his sister Meghan McCain on May 24 and in an online obituary; no cause of death has been disclosed. A Navy veteran who flew A-6 Intruders for six years, McCain later built a long career as a captain with American Airlines. He is survived by his wife, Ashley, his two children, Caroline and Douglas Jr., his grandson Teddy, his mother Carol Shepp McCain and multiple siblings and step-siblings. The McCain Institute extended condolences, calling him a patriot and friend to alumni of the senator’s institute and staff. Private funeral services are planned and a public memorial gathering is scheduled for May 30 at the Princess Anne Country Club in Virginia Beach. Family statements stress his devotion to family, friendship and service.

Tensions flared in northern Spain on May 23-24 when activists from the Global Sumud Gaza flotilla returned after being intercepted by Israeli forces on May 18. Footage from Bilbao airport showed Basque police (Ertzaintza) using batons and dragging activists and supporters, prompting the detention of four people on charges including serious disobedience, resisting authority and assaulting an officer. Authorities said the unrest began when returning campaigners and their supporters blocked an arrivals exit; the regional police have opened an internal inquiry. Organisers say several activists were hospitalised after alleged mistreatment during Israeli custody and are considering legal action. Around 2,000 protesters later demonstrated in Bilbao condemning police conduct, while about 20 other activists received a peaceful welcome in Barcelona. The episode has generated diplomatic rows: Israel summoned Spain’s chargé d’affaires and used video of the Bilbao clashes to criticise the activists, while Spain had earlier protested to Israel over a video posted by National Security Minister Itamar Ben-Gvir. France has barred Ben-Gvir and signalled it may seek EU measures.

A suicide bombing struck a passenger shuttle train in Quetta, southwestern Pakistan, on May 24, killing at least 24 people and injuring around 70 others, officials said. The blast occurred as the train — carrying army personnel and their families returning home for Eid from a nearby military encampment — passed near Chaman Phatak/Faquir Abad station, derailing the engine and multiple carriages; two coaches overturned and caught fire. Images from the scene showed mangled carriages, burning vehicles and damaged nearby buildings. Local hospitals declared medical emergencies and received dozens of critically wounded. The outlawed Baloch Liberation Army (BLA) claimed responsibility, saying it targeted security personnel; Pakistani authorities have condemned the attack and launched an investigation. Senior federal and provincial leaders, including Prime Minister Shehbaz Sharif and Balochistan Chief Minister Sarfraz Bugti, vowed to pursue those responsible. The blast comes amid a long-running insurgency in resource-rich, underdeveloped Balochistan, which has seen repeated attacks on security forces and civilians in recent years.
